Stress spatial distributions, the Gutenberg–Richter and Omori–Utsu laws
Journal of Statistical Mechanics: Theory and ExperimentAbstract We investigate several earthquake models in one and two dimensions of space and analyze in these models the stress spatial distribution. We show that the statistical properties of stress distribution are responsible for the distribution of earthquake magnitudes, as described by the Gutenberg–Richter (GR) law.

Complex networks of earthquakes and aftershocks [PDF]
Nonlinear Processes in Geophysics, 2005 We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviates the need to distinguish main shocks from ...

Dependence of the Omori‐Utsu law parameters on main shock magnitude: Observations and modeling [PDF]
Journal of Geophysical Research: Solid Earth, 2008 We examine the dependence on main shock magnitudemof thepandχparameters appearing in Omori‐Utsu formulaλ(t,m) =χ× (t+c)−prelating the rate of aftershocksλat timetafter a main shock. Observations point out to a significant increase ofpwithm, along with a scaling relationship of the formχ∼ 10αm.

No aftershocks, fluid-driven aftershocks, and Omori’s Law
, 2020 <p>Aftershock sequences follow three empirical laws; Gutenberg Richter, Omori, and Bath. Unless they don't. This raises the question as to why most earthquakes follow empirical laws, while other earthquakes generate few, if any, aftershocks.

Omori-Utsu Law c-Values Associated with Recent Moderate Earthquakes in Japan
Bulletin of the Seismological Society of America, 2009 We investigate the early aftershock activity associated with four moderate earthquakes ( M w 6.6–6.7) that occurred recently in Japan. For each aftershock sequence, we examine continuous high-pass filtered seismograms recorded at seismic stations nearby the main fault to identify as many early events as possible.

Earth and Space Science, 2023 Seismic swarms are defined as a group of earthquakes occurring very close in time and space but without any distinctively large event triggering their occurrence. Up to now no simple law has been found to describe the swarm occurrence rate.

Doğal Afetler ve Çevre Dergisi, 2022 In this study, using the aftershocks that occurred after the March 02, 2017 Adıyaman-Samsat Earthquake (Ml = 5.7) statistical analyzes of b-value and aftershock decay parameter p-value were performed.

ON PROPER TIME OF THE SOURCE OF A STRONG EARTHQUAKE
Геодинамика и тектонофизика, 2023 The physics of earthquakes was contriubuted to by the concept of proper time of the source of a strong earthquake, which is different from universal (calendar) time. The earlier idea of proper time was implicit and has been considered only in relation to

Earth, Planets and Space, 2020 We infer the postseismic deformation mechanisms following the 2011 Tohoku megathrust earthquake via an analysis of onshore geodetic observations. We focus on the temporal decay characteristics of postseismic deformation using continuous time-series data ...
